Three Palestinians were treated for injuries after a tunnel underneath the Gaza-Egyptian border collapsed on Wednesday. Muawiya Hassanein, the director of Ambulance and Emergency Services in the Palestinian Health Ministry said the Palestinians were taken to Abu Yousef An-Najjar hospital in the city Rafah. Medical officials could not confirm reports that a fourth person is still missing underground. Israeli officials have accused Palestinian fighters of using an elaborate network of tunnels to smuggle equipment and personnel into the Gaza Strip.
